- TEST SITE
- Area of exposure: Back and flanks.
- % coverage: Approx. 10% (6.0 cm x 5.0 cm = 30.0 cm²)
- Type of wrap if used: Test material was placed on a wet gauze-layer of a "Cutiplast® steril" coated with air-tight "Leukoflex®" gauze strip which was placed on the rat's back and secured in place using "Peha®-Haft" cohesive stretch tape (8 cm x 23 cm) and additionally covered with a "Lomir biomedical Inc rat jacket" and connnected with a safety pin to the stretch tape.
REMOVAL OF TEST SUBSTANCE
- Washing: Rinsed with tepid water using soap and gently patting the area dry.
- Time after start of exposure: 24 h
TEST MATERIAL
- Amount(s) applied: 2000 mg/kg bw; 21.8 - 25 mg/cm² for males and 18.2 - 19.8 mg/cm² for females.
- Constant volume or concentration used: yes
- For solids, paste formed: No, test substance was applied via a wet gauze layer. - Duration of exposure:
- 24 hours
- Doses:
- 2000 mg/kg bw
- No. of animals per sex per dose:
- 5
- Control animals:
- not required
- Details on study design:
- - Duration of observation period following administration: 14 days
- Frequency of observations and weighing: Clinical signs and mortality rates were determined several times on the day of application and subsequently at least once daily thereafter. Body weight and bodyweight gain were checked weekly until the end of the study.
- Necropsy of survivors performed: Yes - Statistics:
- Means and standard deviations were calculated for bodyweights
The LD50 value was calculated with the aid of a software program according to Spearman, Karber (D. J. Finney; Statistical method in biological assay, 2nd Edition, Griffin, London, 524-530; 1971). The algorithm was taken from L. Sachs (Angewandte Statistik, 6th Edition 1984, pp. 178 ff.).
Where calculation of the LD50 using the software program was not possible or meaningful, an assessment was made based on the applied dose and dose-response curve, respectively.
Results and discussion
Effect levels
- Key result
- Sex:
- male/female
- Dose descriptor:
- LD50
- Effect level:
- > 2 000 mg/kg bw
- Based on:
- test mat.
- Mortality:

Applicant's summary and conclusion
- Interpretation of results:
- other: CLP/EU GHS criteria not met, no classification required according to Regulation (EC) No 1272/2008.
- Conclusions:
- The study was performed in accordance to OECD TG 402 under GLP conditions and is considered reliable. The LD50 was determined to be > 2000 mg/kg bw.
